19 From X-rays to electronsImaging of the MeV neutroncapture line (blue contours) and the HXR electronbremsstrahlung (red contours) of the flare on October 28, The underlying image is from TRACE at 195 Å. The X-ray and γ-ray imaging shown here used exactly the same selection of detector arrays and imaging procedure. Note the apparent loop-top sourcein the hard X-ray contours.(Hurford et al, 2006)
